Philip Seymour Hoffman’s death from an apparent drug overdose over the weekend was an unqualified tragedy, but it has already encouraged young stars to raise their voices on the topic of addiction.

In a lengthy Twitter post, Demi Lovato, who has been quite frank in her discussion of her struggles with addiction, called for an end to the stigma and asked her contemporaries to stop glamorizing drug use in music.

“It’s time people start really taking action on changing what we’re actually singing/rapping about these days because you never know if you could be glamorizing a certain drug to a first time user or alcoholic who could possibly end up dead…” she wrote, before adding, “RIP Philip Seymour Hoffman.. An INCREDIBLE artist who lost his life to this horrible disease.”

Actor Shawn Pyfrom, best known for playing Andrew on “Desperate Housewives,” also revealed on Tumblr this week that he is a recovering alcoholic and a drug addict.

“When news reaches us of a public figure, like Mr. Hoffman, passing away from such a terrible affliction, we tend to get the feeling of a great loss. It is a great loss… but every life is important,” he wrote, adding, “I want to express that I chose to share this about myself because I could not hear of another person being robbed of their life, due to addiction; knowing that I stayed quiet about mine.”
